I need the Force/Energy/Whatever for a person jumping

[JoshuaTheDevastater]

I'm trying to calculate how much Force/Energy or whatever or measure that in for a person who weighs 90 kg (Like 198 lbs. Or something) to jump 20 yards in the air. This is for a different world, so the gravity is 8.1332 m/s, as apposed to 9.807 m/s for Earth.
Please help, I know 20 yards is a lot, but please answer. Thank you.
